One of my customers (using Outlook via Exchange) keeps sending me winmail.dat attachments. I know from experience that this means somewhere the message is being sent as "Rich Text" rather than "HTML".
However he's checked and Outlook is set to use HTML.
Any suggestions? I don't have Outlook installed (I don't think they have a Linux version yet :-), although I think it's possibly at an Exchange level anyway, and I know some people her administer both. It seems to be only affecting me - they haven't explicitly said this but I get the impression they can send attachments to (eg) Hotmail and Gmail which (as far as I know) don't support Rich Text either, so it may be something somewhere as got configured against my email address. But I'm just speculating!
Something else they haven't said, but I can hear them thinking it, is "why don't you just use Outlook like everyone else", so I'd like to show this is a config problem their end not just me being "non-standard".
Grrrrr....

PS: I do have tnef installed so I can extract winmail.dat files but when all they're sending me is screenshots it's a pain not to be able to read them inline in Thunderbird.
They can fix it at their network border by preventing Exchange from using rich text to forward content. Exchange simply loves to meddle with the contents of emails including, but not limited to, using rich text format and messing about with the line length in emails. The specifics depend on the version of Exchange they are running. One side effect that they will have to be aware of is sending calendar entries to other external Outlook users will probably break if they do this. -- ATB, Karl

Hopefully, as the grip that Exchange and Outlook have on email diminishes (with people collecting email on mobile devices etc) they'll be forced to adhere to standards a bit more.
In the meantime I guess we're stuck having to work around it (and MS described the GPL as a cancer!)

I figured I could work that out from their email headers but can't see anything useful, which seems odd? Can't even find a reference to Outlook!

Hmm, this is something they do so I guess that might be a showstopper, although that said I've received .ICS files from them in the past (when for whatever reason they weren't forcing winmail.dat's on me).
I guess I'll have to live with it for now.

Hmm, do you control the mail server it comes in on? You could get it to filter and transform tnef in to the right attachments at that level instead and mitigate the problem - it'll be easier than trying to get them to fix Lookout.

Sadly (well actually not so sadly) not any more; we migrated to Google Apps a year ago and I don't miss the joys of running my own mail server; when it goes wrong (which is pretty rare) I just get on with something else until it works again!
Bit surprised TBird doesn't have a tnef filter built in, but I have just found a "LookOut" plugin so I'll try that. Still won't see the attachments on my phone or within Gmail though.
